Description of EVA Film:

 

EVA film is based on EVA resin which basis to ethylene and vinyl acetate copolymer resin, by adding a variety of modified additives, through melt extrusion made of the rmosetting hot melt film. Not be sticky in normal temperature, easy to operation. Produced by thermal lamination with the bonding enhanced crosslinking chemical reactions, making silicon wafers, glass, TPT multilayer material consisting of one firm bond as the product of solar panels, in actual outdoor applications up to 25 years life. A large number of applications at home and abroad well-proven solar panels, EVA film is the optimum cost performance, it is difficult to alternative packaging materials for solar cells.

Q:What is the melting point of PET plastic film?
PET plastic is the abbreviation of Polyethylene terephthalate in English, referred to as PET or PETP. Polybutylene terephthalate mainly consists of polyethylene terephthalate, two ester PET and polybutylene terephthalate two PBT. Polyethylene terephthalate is also commonly called polyester resin. It is a condensation of terephthalic acid with ethylene glycol and is collectively referred to as thermoplastic polyester, or saturated polyester, with PBT.
Q:Why do you put plastic film on the paved road?
Cover with plastic film to prevent moisture from evaporating. If the moisture is too fast, evaporation will affect the curing of concrete, it will cause cracking, peeling and other phenomena, affecting the strength of concrete.
Q:Can electrostatic generator adsorb plastic film?
An electrostatic generator can be used to adsorb plastic films;ESD (electrostatic discharge generator) is mainly applied to the ESD test of human body metal model for system level electronic equipment, such as mobile phone and computer, including electrostatic generator and electrostatic discharge gun;
Q:Concrete pouring process can use plastic film capping, 12 hours after watering maintenance?
Large volume concrete will be covered and maintained within 12 hours after pouring. At last, thermal calculation should be carried out carefully, and temperature measurement work should be strengthened. Thermal insulation and maintenance shall be adopted to reduce the internal and external temperature difference of mass concrete. It is also important to strengthen the maintenance of concrete. In the construction of mass concrete, it should be covered with pouring edge, and be maintained and maintained after 5 ~ 7d.
Q:Is it good to use PP bag or plastic film?
With asbestos mesh (general dish pack more use of this media) direct contact with the disk, the relative effect is better
Q:Should the film on both sides and back of SIEMENS refrigerator be torn off?
The SIEMENS refrigerator on both sides and the back of the film should be torn off.
Q:What's the best way to eliminate static electricity with plastic film?
Electrostatic elimination is the most complete solution, according to the breadth of the film, in the serious static place, use the appropriate length of the 3024 DC pulsed ion rod, local collocation SS2000 in addition to static rope (cost saving).
Q:Can the barrier in the refrigerator be covered with plastic film?
Just leave the plastic film on the back of the freezer, or the surface of the evaporator line inside the freezer.
Q:Is it possible to lay a plastic film between the roof slab or concrete for waterproofing purposes?
It is recommended that the precast slab be first poured with a diameter of 4mm or more, 200 spacing, two-way C20 fine stone concrete, 40mm thick, and then do waterproof two road, a little bit better insulation layer, and then make surface layer protection.
Q:Is plastic film the same as glass cloth?
The material is different, not to mention the process
PROTECT, is the professional manufacture Enterprise with the largest investment scope, the most comprehensive product Specifications, strong production capacity and the highest sales volume, mainly produce special materials PVB and EVA film for bullet-proof glass, windscreen of the automotive, architectural safety glass as well as solar cell panel.
